U.S. Steel on June 1 appealed three installation permits issued by the Allegheny County Health Department (ACHD) regarding Reasonable Available Control Technology (RACT) at its Mon Valley Works facilities.
In its appeal, U.S. Steel argues that the facilities cannot meet the emission limits that ACHD determined to be RACT. Among other things, U.S. Steel alleged that:
ACHD issued the permit without first receiving a complete application as required.
The terms and conditions of the permit issued April 21 were “substantially different” than what was presented in the preliminary draft, which did not afford U.S. Steel the opportunity to comment on them.
ACHD issued the installation permit even though U.S. Steel did not request to “install, modify, replace, reconstruct or reactivate any source of air pollution control equipment at the facility.”
